Speaking of roots, another root that I am quite fond of at this time of year is Astragalus membranaceus, a Chinese herb that acts as an adaptogen to protect the body from stress, and protects and supports the immune system to prevent colds and upper respiratory infections.  It can be taken daily as a preventative and is safe for children.  It is available in my office as a liquid tincture or capsule.  If you have a medical condition or are taking any medications, please ask your doctor before adding this herb to your regimen.
